ADJUSTABLE WlNDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 416,004, dated November26, 1889..

Application filed August 12, 1889. Serial No. 320,521. (No model.)

To all whom, it may concern.-

.lle it known that I, CHARLEs MEGOW, of the city and county of SanFrancisco, State of California, have invented an Improvement inAdjustable WindoxwSashes; and I hereby declare the following to be afull, clear, and exact description of the same.

My invention relates to that class of window-sashes which are pivoted attheir sides, whereby they are adapted to be reversed to permit ready andeasy access to them from the inside for the purpose of washing them; andmy invention relates particularly to that class of thesepivotally-adjustable sashes in which the inside and outside beads andthe intervening parting-strips are themselves pivoted, so as to adaptthem to be thrown backwardly in the window casing or frame, there byfreeing the sashes.

My invention consists in improved details of the construction,arrangen'ient, and co1nbination in this class of adjustablewindowsashes, as will be hereinafter fully described, and specificallypointed out in the claims.

The object of my invention is to provide a simple and easily-operatedwindow the sashes of which can be readily reversed topermit them to bereached.

Referring to the accompanying drawings for a more complete explanationof my invention,Figure 1 is a perspective view of my adjustable windowsashes and frame. Fig. is a front elevation, the lower sash and thelower portion of the window-frame being in section. Fig. 3 is ahorizontal section 011 line 00 a: of Fig. 2. Fig. at is a view of thesliding connecting-iron L.

A is the window frame or casing. lower sash, and C is the upper sash. Dis the inside bead. E is the outside bead, and F is the parting-strip.These are all mounted in the sides of the window casing or frame in sucha manner as will adapt them to be moved into and out of position, whenin the former position projecting inwardly and overlapping the stiles ofthe sashes, and in the latter position being withdrawn so as to free thesashes. These beads and parting-strip on each side are all pivoted uponcross-shafts G, passing through the window-easing sides near the topthereof, and they are united at their B is the lower ends by means of across-plate II, from which a bar I-one on each side-extends inwardlyinto the sill of the window frame or casing in a suitable groove or seata therein. Now, by pushing outwardly these slide-bars the beads andparting'strips on each side are all moved outwardly together, turningabout their hinged tops as centers and removing themselves from thestiles of the two sashes, which in their normal position they confine toplace, forming grooves in which they move. The slide-bar's have hingedarms i, which are adapted to enter grooves a in the windowsill to holdthem in a posit-ion eitheroutor in.

In the sides of the window frame or casing and opposite the stiles. ofeachsash' are made grooves J, which are faced by separated metal plateson their outer surface, thus forming a kind of T-shaped channel.

In the stiles of each sash are made grooves K, commencing at about theircenters and extending downwardly to the lower bar of each sash. Thesegrooves are faced by separated plates 7v.

L are connecting-irons consisting of long bars, which are fitted J andtravel in the fiang ed grooves J of the window-casing sides and haveshanked buttons or knobs Zprojecting from their centers and fitted inthe flanged grooves K of the sash st-iles. To the upper ends of the barsare connected. the weightcords M of the sashes. These bars are by meansof the shankcd knobs Zconnocted with the sashes, and they form therunners or guides by which the sashes move up and down, being confinedto their seats by the metal flanges or plates j of the grooves J inwhich they run. The shanked knobs 1, which enter the grooves K of thesash-stiles, form pivots about which said sashes are turned in reversingthem, and they also form guides which, traveling in the grooves K of thestiles, enable the sashes to be drawn down within reach after beingturned.

The operation of the device is as follows: The sashes move up and downin the usual manner by means of the weights. They are held in normalposition by means of the beads and parting-strips, which form thegrooves confining them. When it is desired to wash the glass of thesashes, the slide-bars I in the sill of the casin g are forcedoutwardly, thereby swinging the beads and parting-strips on each sidebackwardly on their pivotal centers above and freeing the window-sashes.The lower sash is then turned .about' the shanked knobs Z as centers andpulled down within reach, its grooves K traveling over said knobs. Theupper sash is then likewise manipulated, whereby the outer side of theglass of each sash may be easily reached.

I am aware that in adjustable sashes of this class the inside andoutside beads and the intervening parting-strip have been made movable,so that they might be pushed back out of the way, and thus free thewindowsashes, and I do not claim such, broadly, but confine myself tothe particular improved constructions described. 7

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In combination with the sliding and swinging window-sashes, themovable and connected inside and outside beads and parting-strips oneach side, and a pivotal shaft at the top of said beads and strips,whereby they move outwardly about said shafts as centers, substantiallyas described.

2. In' combination with the sliding and swinging window-sashes, themovable inside and outside beads and parting-strips on each side, thepivotal shaft on which the upper ends of said beads and strips aremounted, the connecting-plate at the lower ends of said beads andstrips, and the slid e-bars extending from said plate inwardly into aseat in the sill of the window-casing, substantially as described.

3. The windowcasing or frame having the grooves J in its sides, withface-plates j and the sashes of the window, in combination with theslide-bars L, mounted in the grooves of the window-casing and havingshanked knobs Z, extending therefrom and journaled in the stiles of thesashes, and the weighted window-cords connected with the slide-bars,substantially as described. j

4. The window easing or frame having grooves J in its sides, withface-plates j, the sashes having the grooves K in their stiles, withface-plates 7.;,in combination with the slide-bars L, mounted in thegrooves of the window frame or casing and having the shanked knobs Z,projecting therefrom and mounted in the grooves of the sash-stiles,whereby said sashes may be reversed and moved on the knobs, and theweighted window-cords connected with the, slide-bars, substantially asdescribed.

5. The window frame or casing having the grooves J, with face-platesj inits sides, and

the sashes having grooves K, with face-plates k in their stiles, incombination with'the slidebars L, mounted in the grooves of the windowframe or casing and having shanked.

knobs Z, mounted in the grooves of the sashstiles, the weighted cordsconnected with the slide-bars, and the movable inside and outside beadsand intervening parting-strips on each side of the window frame orcasing, pivoted at their tops and having a connectingplate and slide-barat their bases, substantially as described.

In witness whereof I have hereunto set in hand.

CHARLES MEGOW.
